Quality of Service
QoS is a technique that is used to manage network resources and guarantee a bandwidth
relationship between individual applications or protocols. A communications network
transports a multitude of applications and data, including high-quality video and
delay-sensitive data such as real-time voice. Networks must provide secure, predictable,
measurable, and sometimes guaranteed services. Achieving the required QoS becomes the secret
to a successful end-to-end business solution.
